Ms Arsanian is under fire, after the photos of her son dressed as Hitler at a Boulder City Chamber of Commerce-sponsored event, “Trunk or Treat,” went viral according to the Las Vegas Review-Journal.

Ms Arsanian, in a private post to a Boulder City Facebook group that has since been deleted, said that the Hitler costume was simply thrown together in haste and does not reflect her or her family’s views.

The mother then compared dressing as Hitler to dressing as fictional evil characters such as Michael Myers of Halloween and wrote that her son chose to dress as Hitler because of his haircut.

“A disgusting person, and raising a kid and teaching other kids?! Wow,” one user posted.

“Proof you can have a college education and not be terribly bright… why the hell did she think this was okay?? And it’s a shame because there’s such a dire need for special education teachers,” another said.

Kirsten Searer, a Clark County School District spokeswoman, said that the district is aware of the social media posts but would not reveal whether Ms Arsanian would face disciplinary action.

Ms Arsanian did not immediately respond to Yahoo Lifestyle’s requests for comment.
